Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processor that combines stirring and grinding functions. Background Technology

[0002] Most commercially available juicers and blenders are equipped with a stirring rod. This allows them to scrape off viscous ingredients by inserting the stirring rod through the feeding port on the lid and manually holding it to scrape the food off the inner wall, thus improving the blending effect. However, this design is problematic. Since the stirring rod needs to be inserted through the feeding port, and juicers and blenders operate at high speeds, this can cause food to splash out and potentially lead to malfunctions due to misoperation. It is inconvenient to operate and carries certain risks. Furthermore, manually holding the stirring rod makes it difficult to adjust the blending intensity according to the actual blending needs, resulting in less effective blending. Utility Model Content

[0003] This utility model provides a food processor that combines stirring and pulverizing functions, aiming to solve the technical problems of existing juicers and blenders having inconvenient stirring rods that pose certain risks during use; and the difficulty in adjusting the stirring intensity and poor stirring effect when operating the stirring rod by hand.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a food processor that combines stirring and grinding functions, comprising:

[0005] The main unit has an upward-opening working slot and a drive shaft located within the working slot;

[0006] The cutter head assembly includes a first body placed in the working groove, a rotating cutter head rotatably connected to the first body, and the rotating cutter head being drivenly connected to the drive shaft;

[0007] The working cylinder cooperates with the first main body and surrounds the outer periphery of the rotating cutter head;

[0008] The stirring assembly includes a second main body installed on the top of the working cylinder, a drive mechanism disposed within the second main body, and a stirring element extending into the working cylinder. The drive mechanism is used to drive the stirring element to rotate and move up and down, and the stirring element is in contact with the inner wall of the working cylinder.

[0009] The detection module is communicatively connected to the drive mechanism. The detection module is used to detect the operating current of the drive mechanism. When the operating current exceeds a preset value, the torque of the drive mechanism increases.

[0010] In one possible implementation, the bottom of the second main body is provided with an insertion part, the top wall of the working cylinder is provided with a through hole that mates with the insertion part, and a first sealing ring is fitted around the outer periphery of the insertion part.

[0011] In one possible implementation, the top surface of the working cylinder has a recessed groove for placing the first sealing ring.

[0012] In one possible implementation, the inner ring of the insertion portion is provided with an internal thread, and the driving mechanism includes:

[0013] The motor is located inside the second main body, and the output shaft of the motor is arranged vertically.

[0014] A drive shaft is connected to the output shaft of the motor and has the freedom to reciprocate in the up and down direction. The outer circumference of the drive shaft is provided with an external thread that mates with the internal thread.

[0015] The stirring element is fixed to the bottom of the drive shaft.

[0016] In one possible implementation, the bottom inner ring of the insertion part is provided with a first limiting ring, the drive shaft has a second limiting ring with a diameter larger than the first limiting ring, the second limiting ring is located above the first limiting ring, the external thread is located on the outer periphery of the second limiting ring, and a second sealing ring is also sleeved on the outer periphery of the drive shaft, the second sealing ring being located between the first limiting ring and the second limiting ring.

[0017] In one possible implementation, the stirring element includes:

[0018] The fixing rod is fixedly connected to the drive shaft;

[0019] Two stirring rods are fixed at both ends of the fixed rod, and the stirring rods extend in the vertical direction.

[0020] In one possible implementation, the top of the fixing rod is provided with a groove, which rotatably engages with the insertion part.

[0021] In one possible implementation, the stirring rod has an arc-shaped rib protruding from the side facing away from the working cylinder sidewall.

[0022] In one possible implementation, the top of the main unit is provided with a power supply base, and the stirring assembly has a downwardly extending contact that is electrically connected to the power supply base.

[0023] In one possible implementation, the power supply base has a sliding inlet on one side of the working cylinder in the circumferential direction, and a power supply pin is provided inside.

[0024] Compared with the prior art, the solution shown in this application embodiment separates the blade assembly from the working cylinder before use. After the food is placed into the working cylinder, the working cylinder and the blade assembly are assembled. At this time, the blade assembly and the stirring assembly are sealed at the top and bottom of the working cylinder to prevent the food from falling out. Then, the blade assembly is installed downwards into the working slot of the main unit. At this time, the rotating blade in the blade assembly is connected to the drive shaft. The main unit is started, and the drive shaft on the main unit drives the rotating blade to rotate and crush the food in the working cylinder. During the crushing process, the drive mechanism on the stirring assembly is started, driving the stirring component to rotate. The stirring component rises and falls synchronously when rotating, which can scrape the food adhering to the inner wall of the working cylinder to the crushing area to achieve full crushing of the food. After the work is completed, the blade assembly, working cylinder and stirring assembly can be removed as a whole. The crushed food in the working cylinder can be poured out by opening the blade assembly. This food processor combines stirring and grinding functions. By adding a stirring component, it enhances the grinding process, resulting in more thorough grinding. Furthermore, the stirring component rises and falls synchronously during rotation, preventing food from adhering to the inner wall of the working drum and hindering processing. This optimizes food processing and improves the user experience. A detection module allows for easy monitoring of the real-time stirring status within the working drum, enabling adjustments to the drive mechanism's torque based on changes in current, thereby improving the stirring effect.

[0040] Please refer to the following: Figures 1 to 5The present invention provides a food processor that combines stirring and grinding functions. The food processor includes a main unit 10, a blade assembly 20, a working cylinder 30, a stirring assembly 40, and a detection module. The main unit 10 has an upward-opening working groove 11 and a drive shaft 12 located within the working groove 11. The blade assembly 20 includes a first main body 21 placed within the working groove 11, and a rotating blade 22 rotatably connected to the first main body 21. The rotating blade 22 is drively connected to the drive shaft 12. The working cylinder 30 cooperates with the first main body 21 and surrounds the outer periphery of the rotating blade 22. The stirring assembly 40 includes a second main body 41 mounted on the top of the working cylinder 30, a drive mechanism located within the second main body 41, and a stirring element 44 extending into the working cylinder 30. The drive mechanism drives the stirring element 44 to rotate and move up and down, and the stirring element 44 adheres to the inner wall of the working cylinder 30. The detection module is communicatively connected to the drive mechanism and is used to detect the working current of the drive mechanism. When the working current exceeds a preset value, the torque of the drive mechanism increases.

[0041] Optionally, the working cylinder 30 can be screwed into the inner ring of the first body 21 by means of a threaded connection, and the second body 41 can be fixed to the top of the working cylinder 30 by means of a threaded connector.

[0042] It should be noted that, Figure 2 Only the drive shaft 12 structure in the main unit 10 is retained, and the rest of the structure is omitted. However, it is not difficult to understand that the drive shaft 12 is the output shaft of the motor in the main unit 10 (which is not the same as the motor 42 in the stirring assembly 40).

[0043] The working principle of the detection module is as follows: When the drive mechanism includes a motor 42 and a transmission shaft 43, the detection module is connected to the motor 42. The detection module can detect the current change during the operation of the motor 42. When the current increases, it indicates that the resistance interference of the food in the working cylinder 30 is large. At this time, the torque of the motor 42 is increased to ensure that the stirring rod 442 can smoothly remove the residue from the inner wall of the working cylinder 30. If the current decreases to the normal value, the motor 42 returns to the normal torque value.

[0044] The food processor combining stirring and grinding functions provided in this embodiment, compared with the prior art, requires the blade assembly 20 to be separated from the working cylinder 30 before use. After placing the ingredients into the working cylinder 30, the working cylinder 30 and blade assembly 20 are assembled. At this time, the blade assembly 20 and stirring assembly 40 are sealed at the top and bottom of the working cylinder 30 to prevent the ingredients from falling out. Then, the blade assembly 20 is inserted downwards into the working slot 11 of the main unit 10. At this time, the rotating blade 22 in the blade assembly 20 is connected to the drive shaft 12. When the main unit 10 is started, the drive shaft 12 on the main unit 10 drives the rotating blade 22 to rotate against the working cylinder. The food processor in the working cylinder 30 is crushed. During the crushing process, the drive mechanism on the stirring component 40 is activated, driving the stirring element 44 to rotate. The stirring element 44 rises and falls synchronously during rotation. During rotation and rising / falling, the working current of the drive mechanism is detected by the detection module, thereby adjusting the working torque of the drive mechanism in real time. This process scrapes food adhering to the inner wall of the working cylinder 30 to the crushing area, achieving thorough crushing. After completion, the blade assembly 20, working cylinder 30, and stirring component 40 can be removed as a whole. Opening the blade assembly 20 allows the crushed food in the working cylinder 30 to be poured out. This food processor, combining stirring and crushing functions, adds a stirring function during the crushing process by adding a stirring component 40, making the crushing of food more thorough. Furthermore, the synchronous rising and falling of the stirring component 40 during rotation prevents food from adhering to the inner wall of the working cylinder 30 and remaining unprocessed, optimizing the food processing effect and enhancing the user experience. The detection module allows for easy judgment of the real-time stirring status within the working cylinder 30, thereby adjusting the working torque of the drive mechanism based on changes in the drive mechanism's current, improving the stirring effect.

[0045] In some embodiments, an improved configuration of the stirring assembly 40 and the working cylinder 30 can be as follows: Figure 2 and Figure 5 The structure shown. See also Figure 2 and Figure 5 The second main body 41 has an insertion part 45 protruding from its bottom. The top wall of the working cylinder 30 has a through hole 31 that mates with the insertion part 45. A first sealing ring 46 is fitted around the outer periphery of the insertion part 45. The engagement of the insertion part 45 with the through hole 31 ensures the stability of the stirring component 44 when driven by the drive mechanism. Since the stirring component 44 extends into the working cylinder 30 through the top wall of the working cylinder 30, the first sealing ring 46 prevents food from entering the second main body 41 from this point, ensuring the normal operation of the drive mechanism.

[0046] In some implementations, an improved embodiment of the above-mentioned working cylinder 30 can be adopted as follows: Figure 2 and Figure 5 The structure shown. See also Figure 2 and Figure 5The top surface of the working cylinder 30 has a recessed mounting groove 32 for placing the first sealing ring 46. Inserting the first sealing ring 46 into the mounting groove 32 facilitates the positioning of the first sealing ring 46, and when the stirring assembly 40 is working, the mounting groove 32 can also restrict the position of the first sealing ring 46, preventing it from moving up and down due to vibration during operation and affecting the sealing effect.

[0047] In some embodiments, an improved implementation of the above-described drive mechanism may employ, as follows: Figure 2 The structure shown. See also Figure 2 The inner ring of the insertion part 45 is provided with an internal thread. The drive mechanism includes a motor 42 and a transmission shaft 43. The motor 42 is located inside the second body 41, and the output shaft of the motor 42 is arranged vertically. The transmission shaft 43 is connected to the output shaft of the motor 42 and has the freedom to move back and forth in the vertical direction. The outer circumference of the transmission shaft 43 is provided with an external thread that mates with the internal thread. The stirring element 44 is fixed to the bottom of the transmission shaft 43.

[0048] It should be noted that the output shaft of the motor 42 is provided with a bar key, the long axis of which is parallel to the axial direction of the output shaft of the motor 42. The inner ring of the transmission shaft 43 is provided with a bar groove that cooperates with the bar key. This enables the motor 42 to drive the transmission shaft 43 to rotate, and also ensures the lifting and lowering of the transmission shaft 43.

[0049] The motor 42 drives the transmission shaft 43 to rotate. When rotating, the external thread on the transmission shaft 43 and the internal thread of the insertion part 45 are engaged, which drives the transmission shaft 43 to rise and fall, thereby driving the stirring piece 44 to rise and fall.

[0050] As a modified implementation, a lifting cylinder can also be provided in the second body 41. In this case, the stirring component 44 is directly fixed to the output shaft of the motor 42, and there is no need to install the transmission shaft 43. During the process of the motor 42 driving the stirring component 44 to rotate, the lifting cylinder drives the motor 42 to lift and lower, thereby realizing the synchronous lifting and lowering process when the stirring component 44 rotates.

[0051] In some embodiments, an improved mating method between the insertion portion 45 and the drive shaft 43 can be as follows: Figure 2 The structure shown. See also Figure 2 The bottom inner ring of the insertion part 45 is provided with a first limiting ring 451, and the drive shaft 43 has a second limiting ring 431 with a diameter larger than the first limiting ring 451. The second limiting ring 431 is located above the first limiting ring 451, and the external thread is located on the outer periphery of the second limiting ring 431. The outer periphery of the drive shaft 43 is also provided with a second sealing ring 47, which is located between the first limiting ring 451 and the second limiting ring 431.

[0052] The remaining part of the drive shaft 43 (i.e., the part remaining except for the second limiting ring 431) can pass through the middle of the first limiting ring 451 and be fixed to the stirring element 44 inside the working cylinder 30. When the motor 42 drives the drive shaft 43 to rotate, the drive shaft 43 moves up and down within the inner ring of the first limiting ring 451. At the same time, the second limiting ring 431 moves up and down inside the insertion part 45. When the second limiting ring 431 moves to the top of the first limiting ring 451 and abuts against the second sealing ring 47, the second limiting ring 431 can no longer move, which can prevent the drive shaft 43 from falling out of the insertion part 45 and ensure the matching relationship between the external thread on the second limiting ring 431 and the internal thread in the insertion part 45. Since the remaining part of the drive shaft 43 moves up and down within the inner ring of the first limiting ring 451, by setting the second sealing ring 47, the food inside the working cylinder 30 can be prevented from entering the insertion part 45 and affecting the moving process of the drive shaft 43.

[0053] In some embodiments, a specific implementation of the above-described stirring element 44 may employ, as follows: Figure 2 and Figure 4 The structure shown. See also Figure 2 and Figure 4 The stirring component 44 includes a fixed rod 441 and a stirring rod 442. The fixed rod 441 is fixedly connected to the drive shaft 43. Two stirring rods 442 are fixed at both ends of the fixed rod 441 and extend in the vertical direction. The fixed rod 441 and the stirring rod 442 can be integrated or separate. Here, we take an integrated design as an example. The two ends of the fixed rod 441 are bent downward to form the stirring rod 442. The side of the stirring rod 442 facing the inner wall of the working cylinder 30 is adapted to the curvature of the inner wall of the working cylinder 30, thereby ensuring that the food adhering to the inner wall of the working cylinder 30 is thoroughly scraped off, improving the crushing efficiency of the food.

[0054] Specifically, the fixing rod 441 can also be set to various irregular shapes, and the number of stirring rods 442 can also be set randomly (i.e., multiple), which can be selected according to the stirring requirements.

[0055] In some embodiments, an improved implementation of the aforementioned fixing rod 441 may employ, as follows: Figure 2 and Figure 4 The structure shown. See also Figure 2 and Figure 4 The top of the fixing rod 441 is provided with a groove 443, which is rotatably engaged with the insertion part 45. When the drive shaft 43 drives the stirring component 44 to rotate, the insertion part 45 is located in the groove 443, which can improve the stability of the rotation of the stirring component 44 and reduce noise.

[0056] In some embodiments, an improved implementation of the stirring rod 442 described above can employ, as follows: Figure 2 and Figure 4 The structure shown. See also Figure 2 and Figure 4 The stirring rod 442 has an arc-shaped rib 444 protruding from the side facing away from the side wall of the working cylinder 30. By setting the arc-shaped rib 444 in the inner ring of the stirring rod 442, the stirring effect on the food in the working cylinder 30 can be improved. Combined with stirring, the food can be crushed, which can improve the crushing efficiency and increase the fineness of the crushed food.

[0057] Optionally, the curved ribs 444 can be gradually inclined upward or downward along the circumference of the working cylinder 30.

[0058] In some embodiments, a specific power supply method for the above-mentioned stirring assembly 40 may be as follows: Figures 1 to 3 The structure shown. See also Figures 1 to 3 The main unit 10 has a power supply base 13 on its top, and the stirring assembly 40 has a downwardly extending electrical connector 48, which is electrically connected to the power supply base 13. After the stirring assembly 40, the working cylinder 30, and the blade assembly 20 are integrated into the main unit 10, the electrical connector 48 on the stirring assembly 40 is electrically connected to the power supply base 13. The electrical connector 48 supplies power to the drive mechanism through the power supply base 13, ensuring the normal operation of the stirring assembly 44.

[0059] Specifically, the power supply base 13 has a sliding inlet on the circumferential side of the working cylinder 30, and a power supply pin is installed inside. When the stirring assembly 40, the working cylinder 30, and the cutter head assembly 20 are installed as a whole, the cutter head assembly 20 is first placed into the working groove 11. At this time, the connecting part is offset from the position of the power supply base 13. Then, the working cylinder 30 is rotated so that the connecting part 48 enters the power supply base 13 from the sliding inlet. At this time, the connecting part 48 contacts the power supply pin, completing the conductive connection. This method facilitates switching between the power-on and power-off states of the stirring assembly 40. Users can choose whether to turn on the stirring assembly 40 according to the actual crushing needs. It is easy to install, simple to operate, and highly safe.

[0060] In this embodiment, the detection module can be a circuit board installed in the second body 41. By installing the circuit board between the power connector 48 and the motor 42, the operating power of the motor 42 can be detected, thereby adjusting the torque of the motor 42.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
